, 'Application-August ll, 1933,, Seria No. 684,729 3' g 3 claims."(creas -'62) Theinvntion relates to' doo'r operating means andparticularly to devices adapted to beattached to-ordinary swingingdouble doors, to insure uniform closing at the predetermined closedposition.

It is a specific purpose to present a construction in the door operatingdevice that will enable the opening ofone door through agreaterar'c thanthe other where required, and which will be adjustable to vary thisdifi'erence to suit individual jobs. I

Another object is to-present-a' construction in closers which willoperate the doors satisfactorily to insure proper overlap of theastragal or weather strip customarily applied tothe vertical swingingedge of one'door soas to overliethe other.

It is also an object to so: perfect the invention that a stock form ofequipment may be produced which will be adjustable to the" variousrequirements of ordinaryuse without requiring'sp'ecial sizes or-fittingswhile yet retaining the advantages above recited. I 7

It is a purpose to enable the production of adevice embodying theinvention at an. extremely low and durable in operation. 7

Additional objects, advantages and features .of invention reside in theconstruction, arrangement and combination iof parts involved in theembodiment of the invention as will appear from the .followingdescription and accompanying drawv ing, wherein, 1

Figure 1 is a top plan viewof a door installation embodying myinvention. r

Figure 2 is a side elevation of thetraveller and its mounting. I

Figure-3 is across section ing the latch. p I

Figure 4 is a detail of the connection between the links and doors.

Figure 5 is a fragmentary bottom view of the connection of the linkswith the traveller.

There is illustrated a garage frame In, including side members II and adoor lintel 12 therebetween atone end. Doors l3-l4 are hinged onrespective sides of the frame Ill, and these may be conventional 'doorshung in the conventional way. The right hand door I3 is adapted to movein advance of the other-in closing and the door, M is provided with anastragal strip IS on its outer face at the swinging vertical edge,projecting beyond the vertical edge of the door to function as a weatherstrip in the customary way. The doorsare shown as being of equal radius,but this is not essential. When closed they meet in abutmentcentrally-of the door opening in the ofthe traveller, show:

weight, eificient frame III, and in a common plane; 0n the lintel l2 andextending inwardly theregis mounted a Y horizontal rectilinear rail I6,which may be asim-u plechannel' bar as in Fig. 3'with its channelledside uppermost, secured to the lintel 'atthe middle of the latter and atright angles thereto Azsup-T of :the" rail port I! for the inner or rearend maybe provided, if desired.

jecting a distance above the railnear the ends, these platesbeingtransversely bored to receive 1 the two pins 2! on 'whichresp'ectiveanti-friction wheels 29 revolve. These wheels are set between and spacedfrom theplates IQ'andare of a width to fit smoothly between the flangesof the channel bar l6. s

Centrally of the bottom plate 22 of-the traveller a downwardlyprojected-stud ,23 is provided; tenoned and threaded at its extremity to:receive a a nut 24 andwasher25 thereabove.

Respective door opening links 25 and 2 are pivoted at their extremitieson the doors [3 and I4 respectively, as will be described, andat theirinner ends on the stud 23. For this purpose, the

links are each formed" withza single aperture therethrough attheir outerends, and over their inner endportions areformed with a multiplicity ofapertures 28 all of a size to receive'the stud] 23 alternativelytherein. The inner ends of the links are crossed with appropriateaperturesgZB. I

alined and with thestud engaged throughthe alinedapertures, a spring 29being confined b,e-.:x, 1'35- tween the washer 25 and the links wherebythe.

latter are heldon the stud and firmly against the platen withoutliability of rattling. The outer.

endof each link is secured pivotally bya bolt 30 to an outstandinghorizontal arm '3! consisting of a fiat plate having a longitudinalseries of aper-' other, and also, if desired one of the brackets may benearer the axis oi the door if desired, in order that such door shallopen further than the other, in case that be desired. And in such casethe link connected to that door is connected nearer I the base of thearm 3| and the other link is connected at such distance from-the base ofthe other arm 3| as will equal the difference in the distances from thelinkpivots on the doors 'in Figure 1. r
